EtherNet/IP Settings Parameters
5.2.2. EtherNet/IP Settings Parameters
The EtherNET/IP Settings configuration page supports the following options.
EtherNet/IP Settings Page
ISDU Data Settings
ISDU Response Timeout
Default: 20 seconds
The time that the IO-Link Master’s EtherNet/IP interface waits for a
response to an ISDU request.
The timeout needs to set long enough to allow all commands within the
ISDU request to be processed.
Valid range: 1-10,000 seconds
Process Data Settings
PDI Data Block Size (To PLC)
Default: 36-bytes
The configurable PDI data block length. Supported optional lengths are:
• 4-bytes (header only)
• 8-bytes (4 bytes data)
• 16-bytes (12 bytes data)
• 24-bytes (20 bytes data)
• 36-bytes (32 bytes data)
PDI Data Block Format (To
PLC)
Default: Word-16
Data format of PDI data block to be transferred to the PLC(s) in Class 1
and/or Write-to-Tag/File PDI Transfer Modes. Supported formats are:
• Byte-8 (8-bit or SINT)
• Word-16 (16-bit or INT)
• Dword-32 (32-bit or DINT)
Note: The Data Block Format is independent of the PDI Data Byte-Swap
Method.
This setting is not used for the SLC, PLC-5 and MicroLogix PLCs
which are always Word-16.
PDI Data Byte-Swap Method
Default: Work (16-bit) byte swap
If enabled, the IO-Link Master swaps the data bytes in word (2 byte)
format or dword (4 byte) format.
Supported values are:
• No byte-swap – data passed through as received
• Word (16-bit) byte-swap – data is byte-swapped in word format
• Dword (32-bit) byte-swap – data is byte-swapped in dword format
Note: The byte swapping must be set correctly in order to convert from IO-
Link (big-endian byte order), to EtherNet/IP (little-endian byte
order).
